A peer (group) is configured only to listen to connection requests, but not to send
connection requests.
After this command is used, the existing peer relationship is interrupted. The peer on
which this command is used waits for the connection request from its peer to
reestablish the neighbor relationship. This configuration can prevent the conflict of
sending connection requests.
NOTE
This command can be used on only one of two peers. If this command is used on the two peers,
the connection between the two peers cannot be established.
5.
Run:
ipv6-family
[
unicast
]
The BGP IPv6 unicast address family view is displayed.
6.
Run:
peer
{
ipv6-address
|
group-name
}
enable
The IPv6 peers are enabled.
After configuring the BGP4+ peers in the BGP view, you need to enable these peers
in the BGP IPv6 unicast address family view.
l
Configuring an EBGP Peer
Perform the following steps on the router on which the EBGP connection needs to be set
up:
1.
Run:
system-view
The system view is displayed.
2.
Run:
bgp
{
as-number-plain
|
as-number-dot
}
The BGP view is displayed.
3.
Run:
peer
{
ipv6-address
|
group-name
}
as-number
{
as-number-plain
|
as-number-
dot
}
The IP address and the AS number of a specified BGP peer are specified.
The AS number of the specified BGP peer should be different from the local AS
number.
If the IP address of the specified peer is that of a loopback interface on the reachable
peer or that of a sub-interface on the directly connected peer, you need to complete
the task of
Configuring the Local Interfaces Used for BGP4+ Connections
to
ensure that the peer is correctly established.
4.
Run:
peer
{
ipv6-address
|
group-name
}
ebgp-max-hop
[
hop-count
]
The maximum number of hops in the EBGP connections is set.
By default, a direct physical link must be available between EBGP peers. If such a
link does not exist, run the
peer ebgp-max-hop
command to allow EBGP peers to
establish a TCP connection over multiple hops.
